IMPROVEMENT IN SMOKE AND SPARK CONVEVERS.

Specification forming part of Letters Patent No. LSLGSS), dated May 19,1574; application filed Mey 12, 1874.

To all whom it may concern: t

Be it known that I, TnoMAs Dn tlonnzo, of the city, county, and State'of New York, have invented a new and useful Improvement in Smoke andSpark Conveyers for Locomotives; and I do hereby declare that thefollowing is a full, clear, and exact description of the same, referencebeing had to the annexed drawings making part of this specification, inwhich- Figure lis a side elevation, partly in section. Fig. 2 is avertical longitudinal section, and Fig. 8 is a vertical transversesection through the escape steam-pipe.

The same letters are employed in all the fi gures in the indication ofidentical parts.

This invention relates to tubular conveyors extending from the uptake ofthe locomotive back over the train, for the purpose of carrying thesmoke and sparks and discharging them behind the tra-in, so as torelieve the passengers from this most disagreeable annoyance, which hasbecome so otfensive since the general introduction into use of soft coalin the generation of steam in locomotives.

The tubular conveyer is made in sections permanently attached to thedilferent components of the train, which are connected as the train ismade up by means of couliiling-pipes.

My improvements consist in the use of, first, coupling-pi pes connectedwith sliding tubes on the fixed tubes by means of a ball-and-socketjoint, which will permit the necessary play of the pipes with the motionof the cars 5 second, a swinging valve having a hole to coliform to theescape-pipes for smoke and steam, and used in combination with anothervalve, which covers said hole when the former valve is raised to closean opening in the top of the conveyertube; third, a curved uptakeextending from the shell of the boiler into the open-mouthed conductorwith auniform and continuous curve, so as to oppose a minimum ofresistance to the draft fourth, a Water-recess inthe conductortube forcatching the sparks.

In the annexed drawings, A is an open fuir nel-mouthed tube on thelocomotive, extending forward of the uptake and back over the cab. B isthe uptake, which, instead of being vertical at the bottom and curved soas to be horizontal at the upper end, as heretofore used, or inclined tothe rear, as has been proposed, I

make of a uniform curve from the point where it emerges from theHue-chamber of the locomotive to its termination in t-he conveycntnbe.The object of this is to reduce to a minimum the resistance incident toa danger in the d1- rection of the draft from vertical to horizontal. Uis a hinged valve used to close the tubular conductor, except where thedraft passes through a hole in the valve, corresponding to the openingat the upper end of the uptake. Vhen this valve is raised it closes ahole of the size of the valve in the upper side of the tube Aimmediately over the mouth of the uptake. When the valve C is raisedanother hinged valve, D, is dropped, so as to cover the hole in thevalve C. When the latter is dropped the valve D is raised, so as tocompletely open the escape-hole in the tube A. This is done by means ofthe arms E and Ef, respectively attached to the valves C and D, andconnected by the rod E2. A rod, E3, extends from the cab to the arm E,so that the engineer can conveniently operate the valves. F is theescape pipe from the steam-dome. It may be straight, as shown in Figs. land 3, with valves to permit the escape of the steam either .into orabove the tube A 5 or this pipe may be curved like the uptake, andfitted with valves Gr and H, operated by rods I, I1, l2, and I3, in allre spects like those of the uptake-valves. K is a sliding or telescopicjoint on the tube A, having a spiral spring, L, pushing it outward. Themouth of this joint is formed as a socket to receive the spherical endof the couplingpipe M, forming a ball-andsocket joint, which will permitthe cars to play laterally or vertically without breaking the continuityofthe conveyer. spring-arm, M', which sustains its weight and holds itin such position that the joint will be formed by merely coupling thecars. Another telescopic section, N, is similarly attached to theforward end of the section A', carried on the tender. Similar pipes andcouplings are extended across the entire train. It is manifest that thejoint eanfbe formed with only one telescopic joint in connection witheach coupling section, but I prefer to use them on each end of each ofthe xed sections of the pipe, as shown.

In order to make a receiver to catch and eX- This joint is supportedupon a tin guish the sparks, which often do much damage by kindlingfires on the side of the track, I propose to bend the tube over thetender, as shown in section in Fic'. l, rIhe sparks striking the curvedtube Will be dciiectcd and thrown down and caught in a bed of Watercarried in thc bottom of the bend, as shown at I). They may be taken outfrom time to time by opening the pipe P and drawing oit' the Water.Fresh Water maybe introduced by a funnel, Q, closed by a lid when not inuse.

I do not intend to claim, broadly, the use of a Water-chamber forcatching sparks in the uptake of alocoinotive, for they are Well known,and the principle has been applied in many different devices. Myinvention is limited to the particular mode of forming a water-chamberin a downward bend of a continuous horizontal pipe, which forms anextension of the uptake.

In operation, when the train is going forward, the Valve O-Will beraised to open the funnel-mouthcd pipe A, so that a current of air willbe established `through the latter, materially assisting the draft. Thenthe train is stationary or going backward the Valve C should be dropped,closing the tube A and permitting the draft to escape vertically fromthe mouth of the uptake.

.Wfhat I claim as my invention, and desire to secure by Letters Patent,is-

1. In combination with the sectional con- Veyer-tube and telescopicjoint and spring L, a connection-pipe, M, forming with the sliding jointa ball-and-sockct joint, substantially as set forth. A

2. In combination with the conveyertube A and uptake B, having ahorizontal discharge, the valves C and I), arranged to operate inrelation to one another, for adjusting the draft, substantially as setforth.

3. In combination with the conyeyentube A, having an open mouth, theuptake B, forming a continuous curve from its point of einer gence fromthe flue-chamber to its mouth in thc conveyer, substantially as shown.

4. The Water-recess I?, formed in the con- Veyer-tube by curving thesame, substantially as set forth.

In testimony whereof I have signed my naine to this specification in thepresence of two subscribing witnesses.
